随着综合能源系统复杂程度的增加，系统对部件耦合的要求也越来越高，这增加了系统的不确定性因素，因此，建立综合能源灵活性评价指标体系和评估模型是提高综合能源系统灵活性的关键前提。首先，分别从系统级和局部级来构建综合能源系统灵活性资源的指标评估体系；然后，综合考虑经济性、环保性、安全性等多方面因素，结合层次分析法、熵值法及模糊评价法搭建综合评估模型，并通过具体场景下的8种灵活性资源的调度方案进行指标权重的雷达图分析和模糊综合评价。结果表明：设置的灵活性资源调度方案中，灵活性得分最高的为燃气内燃机＋燃气锅炉的调度方案；但是考虑到经济性、环保性、安全性等多个方面，燃气内燃机＋热泵＋水蓄能、燃气内燃机＋热泵＋储能电站这2个调度方案更为突出。

As the complexity of integrated energy systems increases, so does the demand for component coupling, leading to heightened system uncertainties. Hence, establishing an evaluation index system and assessment model for the flexibility of integrated energy is a crucial prerequisite for enhancing the flexibility of these systems. Initially, this paper constructs evaluation systems for integrated energy system flexibility resources at both the system-wide and localized levels. Then, integrating economic, environmental, and safety factors, this paper employs the analytic hierarchy process, the entropy method, and fuzzy evaluation to develop a comprehensive evaluation model. This model is used for radar chart analysis of index weights and fuzzy comprehensive evaluations based on scenarios implementing eight different flexibility resource scheduling schemes. Results indicates that among the set of flexibility resource scheduling schemes, the highest flexibility score is achieved by the scheme combining gas internal combustion and gas boilers. However, when considering multiple factors such as economic viability, environmental impact, and safety, the two scheduling schemes, gas internal combustion engine combined with heat pump and water energy storage, and gas internal combustion engine combined with heat pump and energy storage station, are more prominent.
